Currently looking to improve your company’s data workflow
I am currently working as a Senior Statistical Programmer Analyst in Menlo Park at GRAIL, Inc and love getting challenged at my current role. I have a level of expertise in both R and Excel that helps me both manipulate and analyze data as well as automate monthly tedious tasks. With the mind of a tutor, I make sure to document everything and answer questions quickly and efficiently when I explain my methodology to coworkers or clients. I am reaching out to companies and teams with needs for data science improvement to reduce human error and increase efficiency. Reach out to me if you have a project I can work on or just a conversation.
